There is theory and then reality and the ideal vs what is.
Track is a sport that really forces you to make the most of what you have and utilize what resources you may not know are available to you.
I am not sure if you are doing any massages yourself but you might look into a place that is teaching massage therapy or some therapies and the students might be more than happy to get valuable experience working on athletes. Teach the athletes to do things like self massage, stretching with ropes and get any kind of roller you can get your hands on. Hydro therapy is free if you have a shower.
Another thing you might be able to do is find an organization willing to give you some financial support or think of some kind of fund raising. IMO teaching the athletes to have some interest in what they are trying to achieve can be a long term lesson which transcends their time in sport.
